DISCUSSION
TODAY THROUGH WEDNESDAY...
HOT AND DRY CONDITIONS WILL EXIST INTO THE WEEKEND AS A RIDGE OF
HIGH PRESSURE BUILDS OVER THE REGION. HIGH TEMPERATURES DURING
THIS TIME WILL BE IN THE UPPER 80S TO 90S, WITH POTENTIALLY A FEW
100 DEGREE READINGS OVER THE PLAINS ON SATURDAY (MEDIUM CHANCE).
RELATIVE HUMIDITY VALUES WILL ALSO BE LOW, MAKING IT A DRY HEAT.
WHILE NO PRECIPITATION IS FORECAST DURING THIS TIME, THERE WILL BE
A DRY COLD FRONT PASSAGE THIS AFTERNOON AND EVENING THAT BRINGS
BREEZY NORTHWESTERLY WIND GUSTS AROUND 15 TO 30 MPH TO THE AREA.
THE COMBINATION OF THESE WINDS, HOT TEMPERATURES, AND LOW HUMIDITY
WILL CAUSE ELEVATED FIRE WEATHER CONDITIONS ACROSS MUCH OF THE
AREA THIS AFTERNOON AND EVENING, WITH CRITICAL FIRE WEATHER
CONDITIONS OVER PORTIONS OF FAR EASTERN MONTANA INTO WESTERN SOUTH
DAKOTA AND NORTH DAKOTA. WINDS WILL BE LIGHTER ACROSS THE AREA
FRIDAY, THOUGH STILL BREEZY OUT OF THE WEST AROUND PARK, SWEET
GRASS AND WHEATLAND COUNTIES IN MONTANA. SATURDAY INTO SUNDAY,
BREEZY NORTHWEST TO NORTHEASTERLY WINDS WILL SPREAD BACK ACROSS
THE AREA WITH GUSTS AROUND 10 TO 30 MPH, STRONGEST OVER SOUTH-
CENTRAL MONTANA. ONCE AGAIN, THESE WINDS COMBINED WITH HOT
TEMPERATURES AND LOW RELATIVE HUMIDITY WILL RESULT IN PERIODS OF
ELEVATED FIRE WEATHER CONDITIONS. TAKE CARE TO NOT CAUSE A SPARK
TODAY THROUGH THIS WEEKEND.
WARM TEMPERATURES CONTINUE NEXT WEEK WITH HIGH TEMPERATURES
GENERALLY IN THE 80S AND 90S. WHILE MOSTLY DRY CONDITIONS WILL
CONTINUE INTO MONDAY, THE CHANCE OF PRECIPITATION INCREASES
TUESDAY INTO THE SECOND HALF OF THE WEEK AS BETTER ATMOSPHERIC
MOISTURE COMBINE WITH A FEW PASSING SHORTWAVE TROUGHS ROUNDING THE
RIDGE OF HIGH PRESSURE ALOFT. DURING THIS TIME, THE HIGHER
RELATIVE HUMIDITY VALUES WILL LIMIT THE RISK OF FIRE WEATHER
CONDITIONS, HOWEVER, THE RISK OF LIGHTNING STARTS MAY INCREASE
SHOULD THE MORE FAVORABLE THUNDERSTORM PATTERN DEVELOP.
OTHERWISE, HAZY SKIES WITH PERIODS OF SURFACE SMOKE WILL CONTINUE
LATE THIS WEEK INTO NEXT WEEK. FOR TODAY, THE COLD FRONT WILL
BRING A PERIOD OF HIGHER SURFACE SMOKE CONCENTRATIONS TO THE AREA
THIS MORNING INTO TONIGHT. FOR THE LATEST AIR QUALITY INFORMATION,
VISIT AIRNOW.GOV. LA
AVIATION
SMOKE WILL BE THE MAIN IMPACT FOR AVIATION INTERESTS OVER THE NEXT
36 HOURS. EXPECT INCREASED SMOKE ACCUMULATIONS AS WESTERLY WINDS
INCREASE THIS AFTERNOON (GUSTING TO 25KTS AT TIMES). SURFACE
VISIBILITIES MAY DROP TO AROUND 5-6SM AT TIMES, INCLUDING KBIL AND
KSHR TERMINALS (POSSIBLY KLVM). SLANT RANGE VISIBILITY WILL
DECREASE THROUGH THE DAY TODAY AS WELL, IMPACTING MOUNTAIN/PASS
VISIBILITY AS WELL. OUTSIDE OF THE SMOKE, VFR CONDITIONS WILL
PREVAIL. CHAMBERS
